Three Utah horses have tested positive for West Nile Virus. Dr. Warren Hess is the assistant state veterinarian at the Utah Department of Agriculture and Food. He says they’ve been dealing with West Nile Virus in horses since about 2003, with as many as 60 horses contracting the virus in a single year.
“Vaccination has certainly been a significant help in preventing this disease." he says. "All three of the horses, and the vast majority of all horses that have come down with this disease have been unvaccinated animals.”
